Continuing... Source diving tells me that exit-hook is a REPL-only feature. So I'm back to the idea of creating a module-level variable that exists while the module is in memory, and then calling library_end() when that variable is GC'd. But I can make it more schemey by using guardians and after-gc-hook as you suggested. Thanks, Mike Gran
